Filed: 1988-08-20
Granted: 1993-12-15
Abstract: In digital signals transformed into a frequency domain, inaccuracies occur in the structure of the reproduced video signals due to rounding errors in the calculation of the coefficients with a shortened number of digits. 
<??>The invention provides a remedy in that the range of numbers of the direct component is transferred into the range of numbers of the alternating components and thus a greater range of numbers is available for the alternating components for the common processing of the direct and alternating components. 
<??>The invention can be used in digital systems with block-by-block processing in which a rounding of the spectral coefficients is carried out due to a limited number of bits in the calculation.

Granted: 1993-02-17
Abstract: The introduction equipment consists of an inner sleeve (10), an intermediate sleeve (20) and an outer sleeve (30), which are made of flexible material and surround each other in a coaxial manner. The inner sleeve (10) has a proximal end section (11) with handle (12) and a thickened distal end section (13), which tapers conically towards its free end and bears a proximal outer shoulder (15). The intermediate sleeve (20) has a proximal end section (21) and a distal end section (22), whose outer diameter is at least as great as the outer diameter of the proximal outer shoulder (15) of the distal end section (13) of the inner sleeve (10). The outer sleeve (30) has a proximal end section (31) with handle (32) and seals (34) and a slightly conically tapering distal end section (33) which can be radially elastically expanded, the outer diameter at the free end of the distal end section (33) of the outer sleeve (30) being slightly smaller than or equal to the outer diameter of the end section (13) at its outer shoulder (15). In this arrangement, the cross-section of the introduction equipment increases from the distal end gradually and continuously, which allows the introduction equipment to be inserted without difficulties into the opening of a vessel. The intermediate sleeve (20) prevents the withdrawal of the inner sleeve (10) after the positioning of the introduction equipment, while it slightly widens the distal end section (33) of the outer sleeve (30) and passes through the proximal end section (13) of the inner sleeve (10).

Filed: 1988-12-02
Granted: 1996-09-18
Abstract: A substrate voltage bias generator is disclosed including a charge pump whose output is clamped during charge pump capacitor charging cycles to zero volts thereby eliminating a voltage drop associated with prior art clamping diodes. The charge pump further includes a stand-by and booted mode, the stand-by mode providing a first level of output current at a specified generated substrate bias voltage and in the booted mode generating increased output current and voltage. The increased voltage is generated across the charge pump capacitor by a second capacitor that is only operative in the booted mode and whose charge is shared with the charge pump capacitor thereby developing a higher voltage across the charge pump capacitor. The output voltage generated by the substrate bias generator is detected and if it is too low a voltage, the booted mode is turned off. An external signal determines whether the stand-by mode or booted mode are selected.

Title: Prioritysequencing for hydraulically operated turnwrest plough
IPC: A01B3/42
Filed: 1990-05-02
Granted: 1993-08-25
Abstract: The invention relates to a follow-up control or priority circuit for a turnabout plough with plough-frame pivoting, the turnabout plough having a double-acting rotary cylinder for the rotation of the plough frame and a double-acting pivoting cylinder for pivoting the plough frame in and out. The object on which the invention is based is to provide a follow-up control, by means of which the sequence of movements of the cylinders can be controlled, in particular without the fear of pressure losses on the rotary cylinder or operating faults, and whilst at the same time avoiding throttle valves which have to be adjusted specially to the cylinders used. The object is achieved, according to the invention, in that the return line of the rotary cylinder has a non-return valve which is so controlled as a function of pressure that it opens the return line only when a pressure of the hydraulic fluid exceeding a predetermined threshold value is built up in the corresponding control line, the threshold value to be exceeded by the pressure in the control line being predeterminable in a pressure-dependent switching member outside the feedline of the rotary cylinder.

Abstract: 2.1. Subscriber devices in the form of answering machines with information recording, call forwarding and remote interrogation are known. If the owner of the answering machine is travelling, the call signal, after the message of the caller has been recorded, can be automatically forwarded to a paging receiver via the European paging service. The answering machine contains an automatic dialler for forwarding the call. Furthermore, a paging service (City-Ruf) is known in which not only paging signals but also digits and short text (Display-Paging) are transmitted and displayed on the display device of the paging receiver. 2.2. Using a network gateway from the line-connected telecommunications network to a radio paging service, the novel subscriber device provides for fast information transmission of messages temporarily stored in the subscriber device. For this purpose, the subscriber device contains, in addition to the additional buffer store, a microprocessor which, using stored dialling information items, sets up a connection to a paging receiver and then reads out the temporarily stored message. 2.3. The novel subscriber device can be used in all communication networks for switched connections and ensures that a called subscriber who is travelling can respond quickly to a call. <IMAGE>

Abstract: Parmi les opérations de soudure exécutées par un robot soudeur, l'opération de soudure à superposition multicouche est très importante, car elle permet de garantir la résistance de la zone de soudure. Cette opération pose toutefois nombre de problèmes techniques. Selon la présente invention, afin d'exécuter la soudure de la première couche, on détermine une ligne droite ou courbe approximative entre des points d'apprentissage, et on calcule les points sur la ligne droite ou courbe approximative en fonction des distances des points d'apprentissage, chaque passe de soudure effective étant alors définie par ces points. En ce qui concerne les lieux géométriques de la soudure à partir de la soudure de la deuxième couche, on détermine par le calcul la direction et la quantité de décalage, en fonction des deux points définis comme étant le point de départ et le point d'arrivée de soudure pendant l'apprentissage pour la soudure de la première couche et des deux points de référence indiqués dans le but de définir la direction du décalage. On effectue la soudure à superposition multicouche après avoir calculé de la sorte les lieux géométriques de soudure à partir de la soudure de la deuxième couche. Afin de commander la position du chalumeau de soudure pendant la soudure à partir de la deuxième couche, on détermine les lieux géométriques de soudure en fonction du lieu géométrique du chalumeau pendant la soudure de la première couche et de l'angle de rotation donné de l'extérieur du chalumeau de soudure, et on fait tourner ensuite ledit chalumeau d'un angle donné autour d'un vecteur de direction d'avance déterminé en un point d'apprentissage, en calculant les donnés de position. On effectue la soudure à partir de la deuxième couche en fonction des données de position ainsi déterminées. Ces opérations permettent d'effectuer la soudure de la première couche et les passes de soudure successives, c'est-à-dire une soudure à superposition multicouche, avec une grande précision.
